Be it known that I, JAMES A. CUMMISKEY, against which the stick issupported during a citizen of the United States, residing at Clothesawing operation. A. verdale, in the county of Sonoma and State er 12and the guides 13 14 are nnoi' California, have invented new and usefulmediately 1n advance of the normal pendent Improvements insawing-Machines, of which position of the saw and saw frame. Attached tothe saw-frame is an angular arm or My invention re ates to an improvedmaguide which is adapted to be gras ed by the chine for sawing Wood intoscuitable lengths operator to oscillate the saw and w ch is also andsizes for burning in stoves, furnaces, and ada ted and adjustable as aguide and sto to dretermine the particular length ofthe cut. The objectof my invention is to provide a As here shown, this arm and guide memberis simple, practical, portable machine of large made in two sections 1516, these sections capacity which can be moved readily from havinghorizontally-slotted portions lengthplace to place and be ready for workat an wise ad Justable by means oi the set bolts and instants notice andwhich can takelogs or nuts 17 and a drop portion provided with a olesor" any length up to two feet more or suitable stop member 18, w chisadapted when the saw-frame hangs normally to arrange itself directlyin the path of a timber which may be shoved across the roller 12 andagainst the guides 13 14. 's stop member 18 is movable across anadjustable bearingblock 19, secured to the sidef the frame A oppositethe point of entry into the machine of the logs to be cut.

The block 19 is metal-shod, as likewise is the stopl member 18, sincethe impact of the lengths, and, if desired, convey these lengths tosplitting devices, and which splitting devices are herein shown asoperated from the sanie source of power used to drive the saw.

The invention consists ofthe parts and the construction and thecombination of parts, as hereinafter more fully described and claimed,having reference to the accompanying drawings, in which` Figure l isside elevation of my sawingmachine. Fig. 2 is an end view or" same.

priately mounted, if desired, on wheels 2, so as to e easily moved fromone (place to another. of the machine them away.

I haveshown the block 19 as faced with a plate or bar 20, made of ironor steel and erforated to`ieceive the bolts 21. The hea s of shaft 4,Journaled in frame A This sawthe bolts 21 are countersunk into theplate,

frame may be of any well-known pattern and is provided with the top andbottom drivepu le rs 5 6, the pulley 5 being mounted on the s aft 4 andthe pulley 6 on the shaft or arbor 7, which carries t e circular saw 8.The pulleys 5 6 are'connected by a belt 9.

are adjusted so that the dierence between the saw8 and the stop 18equals two feet, and a block 19 of the desired thi kness is inserted andlocked in place.

The parts 19, 20, and 21 are here shown as removable, since they wouldotherwise be in the" way of the incline conve er 22, which is pir/'otedat the up er end near the rear of the frame A and is a apted when themachine is set up for work to have its forward end to drop down belowthe sawandthe ends of the sawed sections. However, when the machine isbein` moved the depressed end of the conveyei' is lifted up and heldclear of the ground by any appropriate means, as shown at '23. Thisconveyer 22 may be of any appropriate' pat.- tern. 'Asis hereshown, ithas aslottedtrou h in which theiiights 24 operate to carry t e the shaft4 and is prevented from len lthwise movement on the latter by suitab estop means. The shaft 4 is driven from an apthi'ough thel medium of thedrive-pulley 10.

The logs or poles or sticks of wood to be sawed are delivered into theath of the saw upon a roller-frame 11, which is detachably connectedwith the frame A and ada ted to extend laterall r thereof.. The stic vsare pushed forward onto a roller 12, journaled in irame A and disposedparallel with the plane of the saw. Adjacent to the inner end ofthe andthe 'boltsdextend through the -block 19 'IOO similar' sprocket 27,journaled in the lower end of the conveyentrough.`

Power to operate the llights of the conveyer 1s transmitted from shalt 4by the following connections: A. belt 28 passes aroundl apulley 29 onshaft 4 and a corres ending pulleyv SO on a counter-shaft 31. (lounterlshaft 3l carries a smaller gear 32, meshing the larger gear 33 on theshaft 34. From shaft 34 motion is transmitted to shai't25 by a suitablebelt or chain 35, passing over cor'- respondinif pulleys or sprockets onthe two shafts. lhe counter-shaft 31 is preferably provided with abalance wheel 36 to give steadiness to the movement of the severaldevices and revent shockto or racking of the parts. noperation the logsto be cut, which have been'placedy by suitable means on the lateralconveyer 11, are pushed forward into contact with the stop 18 andpressed against the guides 13 14. The operator then takes hold of thearm 15 and draws the sawframe and saw forward in the manner of suchsawing devices to saw eff ya block. This movement of the saw-framecarries the stop 18 out from between the end of the stick and theadjoining surface of the supporting-block 19, leaving `the severed blockfree to drop onto the conveyer 22 to be carried upward thereon by theflights and discharged at the rear end of the machine.` The forward endof the frame A is open at the bottom to allow the conveyer 22 to dropdown into a suitable position to receive the sawed lengths of wood.

he end of the conveyer is provided with a metal hopper portion 37,inclosing the end and partly inclosing the adjacent sides or' theconveyor, so that all the blocks are directed immediately down into thepath of the flights. The iront portion of this hopper 37 isilanged orbent over, as at`38, to engage the frontsof the frame A and form a stopor support for the frontend of the conveyor 22 when it is dropped downinto o ierative position.

In the type of mae ine herein shown I have associated certain devices bywhich the blocks mayl be split, if desired, and in such machine thesawe-d blocks from the conveyer 22 are discharged from vthe rear of themachine adjacentto the splitters 39, which operate in vertical guides4() in the frame A, and which s litters are driven from the same sourceo power as the saw and the conveyer 22. These s )litters are arranged inlarge machines 'wit 1 one at each side of the machine, so that two ormore men may be constantly employed taking the sawed blocks as theyaredelivered from the saw and placing them underneathA the splitters. Theses litters-are made with a back guide portion, ere

ermee shown as vertically channeled to aecommodate the guides 4() andwith a front or i'or ward knife or wedge portion by which the actualsplitting is done.

I prefer to use the removable blades 41, se cured in pla-ee by asuitable means, as the bolt or bolts 42, whose heads are protected bythe guides 40. The reciprocation of a splitter is here shown as effectedby a toggle i 43, having one member pivoted to the split ter and theother to the Itop of the vframe A, and by a connecting-rod 44, extendingfrom the joint of the toggle to a crank 45 on the shaft 34. Thus it isseen that the crank 45 4 and the splitter are given a verticalreciprocal'rom the stationary tory movement to and supporting-block 46.In this machine all the moving partssuch as the saw, the conveyer forremoving the sawed lengths, and the splitters-are driven from the samesource of power.

The machine is compact, and by employing a balanced counter-shaft, asshown, I am able to operate with comparatively little shock andvibration and with a noticeable absence of break-downs so liable tooccur in machines of this character.

By using the adjustable sto member 18 and the removable block 19 canquickly adapt the same machine to cut any desired length of' block. Byusing a stop device such as 18, which is movable out from the end or'the timber to be sawed after the same has been placed into ositionbeforethe saw, I avoid all danger oi) pinching the saw or having the blockstick and refusing to drop down when sawed off. It isl a source offrequent annoyance in machines-em'loying a fixed stop to regulate thelen th'o, the eut by reason of the sawed lengt i having to drop betweentwo vertical stationary walls, as. it were, since a tendency of thesevered section is for one of its ends to drop quicker than the otherandso for the section to ,bind against the stop and the saw, withtheresult that a strain is put on thesaw and saw-frame, twisting thesaw-frame or else getting the saw out of a true plane, or both. By thismachine I am able to and have sawed poles or logs forty feet in lengthand up .to two feet in diameter. Having thus described my invention,what I claim, and desire tosec'ure by Letters Patent, is A 1.
